We are given the sequence 1/2, 2/3, 3/4, 4/5, 5/6. In this case, we are asked to determine the formula that represents the sequence. We can use trial and error to determine the formula. It is seen that this is not an arithmetic nor a geometric sequence. The sequence that makes sense here is A. an = n/(n + 1)

I would pick A because if you look and plug in, you would get all your answers. A)an=n/(n+1) n= 1,2,3,4,5 a(1) = 1/(1+1) =1/2 a(3) = 3/(3+1) = 3/4

If h(x) = 6 - X, what is the value of (h*h)(10)?

Vikentia [17]

The value of $\bold{ h(h(10))=10}$

<u>Solution:</u>

Given: $h(x) = 6 - x$

To find: The value of (h*h)(10)

We know that, $(h*h)(x)=h(h(x))$

which is,

$\Rightarrow h(h(x))=6-(6-x)=x$

On solving we get,

$\Rightarrow6-6+x=x$

So, for x = 10 it will be,

$h(h(10))=10$

Hence, the required value is 10.

What do I do on this?

stiks02 [169]

All you do is measure it with a ruler and for every 1 cm you get multiply it by 8.5ft.
so for example if you got 6cm then you would multiply it by 8.5ft and your answer would be 51ft.

A standard deck of cards contains 52 cards. One card is selected from the deck. (a) Compute the probability of randomly selecti

Masja [62]

Answer:

a) 1/2 = 50%

b) 3/4 = 75%

c) 1 / 52 or 1,9%

Step-by-step explanation:

In a standard deck of cards, there are 52 cards in total:

13 are hearts, 13 are diamonds, 13 are clubs and 13 are spades.

(a) Compute the probability of randomly selecting a club or spade

How many cards are a club or a spade?

C = 13 clubs + 13 spades = 26 cards

Out of the 52 total, that means that:

P (club or spade) = 26/52 = 1/2 = 50%

(b) Compute the probability of randomly selecting a club or spade or heart. 

How many cards are a club or a spade?

C = 13 clubs + 13 spades + 13 hearts = 39 cards

Out of the 52 total, that means that:

P (club or spade or heart) = 39/52 = 3/4 = 75%

(c) Compute the probability of randomly selecting a two or diamond.

There's only ONE two of diamond in regular deck of cards, so...

P(2 of diamond) = 1 / 52 or 1,9%
